计算结果表明:①宅基边坡伤亡性黄土崩塌的稳定性随谷缘坡体坡度的增大而降低;
The results indicate that the stability of the landfall reduces with the increase of gradient of it .

以5个典型宅基边坡伤亡性黄土崩塌为例,利用塑性极限分析和极限平衡法,推导出了此类黄土崩塌的稳定性与其坡度之间的关系。
Taking five representative casualty loess landfalls on the house side-slope as examples , applying the method of limit analysis of soil plasticity and the ultimate equity method , the equation of the stability and gradient of the landfall is derived .

通过宅基边坡伤亡性黄土崩塌变形破坏的地质力学模式分析,将此类崩塌分为斜坡谷缘拉裂谷缘坡体蠕动短滑带形成并贯通崩塌土体剪出4个阶段。
On the basis of the geomechanical model for slope deformation and destruction , the developmental process of this landfall is divided into four stages , which are valley-side margin ripping , margin slope creeping , the short slip belt being formed and pierced , and the landfall befallen .
